Invertebrate Hearing and Bioacoustics

Cephalopod Hearing Research

We are currently looking at the hearing and neuroanatomy of squid and cuttlefish including their sensitivity to near-field particle motion stimuli.  Upon discovery that squid can detect sounds we are investigating if and how they might use this cue.

Current Projects

Sound Detection in Squid

Quantifying the acoustic sensitivity of the longfin squid (Doryteuthis pealeii) using near-field acoustic and shaker-generated acceleration stimuli.

Past Projects

Sedating Cephalopods

Methods to non-invasively anesthetize Doryteuthis pealeii, the longfin squid, for up to 5 hrs using a 0.15 M magnesium chloride (MgCl2)-sea water solution.

Reviewing hearing

Book chapter in press

We reviewed the definitions of hearing reminding folks that:

"There is no inherent reason why the definition of 'hearing' should be taxon specific.  It arguably should be based on the ability to detect acoustic stimuli per se and on the ability to analyze acoustic properties of a stimulus.  Thus, this should not be a discussion about whether hearing fits squid perceptual mechanisms but whether squid perceptual abilities fit the broader scope of 'hearing.'
